VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 244,380, dated July 19, 1881.

Application filed May 9, 1881.

To all whom it may concern:

Be it known that I, JOHN G. CRAWFORD, of Douglass, Fayette county, Iowa, have invented a new and useful Improvement in Vehicle- Springs, of which the following is a specification.

My invention consists in the use of a coiled spring with suitable means of attaching the body or box of the vehicle to the same, and a method of securing the ends of the steel band forming the coiled spring without weakening it by holes for bolts or rivets. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 shows the spring applied to a wagon, and Fig. 2 a detail view of one of the springs.

Similar letters refer to similar parts in both views.

A is a standard bolted or otherwise firmly attached to the axle of the vehicle. Two similar circular plates, G, are firmly joined together (leaving a space between them a trifle larger than the width of the coiled spring) by means of three pins, 1) E F, the center one, D, projecting so as to allow the plates to revolve in bearin gs in the upper part of the standard (N0 model.) 7

A. A steel ribbon or band is bent at one end, H, so as to fit around and between the pinsD and E, and then coiled, as shown by the dotted line in Fig. 2, and the other end bent down, 0 so as to catch against the base ofthe standard A at I. From the pintF a link or strap, K,

connects the body or box of the vehicle with the spring.

The action of the spring is simple. A load 5 in the vehicle tends by means of the links K.
